Problems with a spinbox Qt creator

[cmdg]

Hi Im a new user of qt creator and Im creating my first interface, I need to reset the values of 16 doublespinboxes to 0 with a botton, I dont know how to set the values of a spinbox to 0 in qt creator

[wysota]

spinbox->setValue(0);

spinbox->setValue(0);

To copy to clipboard, switch view to plain text mode 

[cmdg]

Thanks I probe it but the program show me '->' is not a pointer. What should be the problem?

[airglide]

there are two way of doing it

Spinbox = spin;
spin.setValue(0);
 
//or if you do it with a pointer
// in the Header: Spinbox *spin;
 
spin = new Spinbox;
spin->setValue

Spinbox = spin;
spin.setValue(0);

//or if you do it with a pointer
// in the Header: Spinbox *spin;

spin = new Spinbox;
spin->setValue

To copy to clipboard, switch view to plain text mode

How are you creating QSpinBox? Are you writing code or using Qt Designer?

[cmdg]

Im working on qt designer. The problem is that I put a value manually in each one of the 16 spinboxes and I need to put all in 0 with a button like a reset but the codes I found in the web dont work.

[Santosh Reddy]

Set the QSpinBox object name by right click on QSpinBox in Qt Designer and "Change objectName", set to "spinXX", where XX is the number of spin box.

Then write a slot with code like spinXX->setValue(0); for all the spinboxes, and then connect this slot to the pushbutton clicked signal

[cmdg]

I've already connected that slot to the pushbutton clicked signal but I also need to put spinXX->setValue(0) inside the function and it doesn't work. This is my code

int MainWindow::new_file()
{
angle_1->setValue(0.0);
}

It show me again the same mistake: /home/vivi/Documentos/tesis/Codigo Interfaces Vivi/MSR-build-desktop/../MSR/mainwindow.cpp:310: error: base operand of ‘->’ is not a pointer
